Designed as an evolutionary step in concealed fixed blade knives, Pentagon FX Covert is ideal for discreet carry. It features a double-edge CYRO S35VN full-tang steel blade, removable G10 handles and a minimalist GRN sheath compatible with SOG's next-generation Universal Mounting System. A lot of innovation is in this small package. It's modest in size, but big in capability. Includes sheath.
